I use no-knot medium from basspro. They are handy when trolling if you are experimenting with different weight jigs. This picture is larger than the actual item.

I did not like the Stabors

It is actually faster to change single jigs by not using either. Just tie the overhand knot with the loop. I use them when double rigging pulling if I am experimenting with jig head color or weight. I keep a selection of jigs in my tackle box with no knots already cliped to them. If I break off I can just tie a double overhand knot and cinch it tight.
